[cctalk] Re: European wire size (slightly off topic)

From the US, the UK is (probably), in Europe ? Beyond simply using US wire / sizes, and ignoring the definition of wire/cable, the main things you can source in the UK are: Tri rated wire https://www.elandcables.com/cables/tri-rated-h05v2-k-h07v2-k-cable#ProductL… 0.5 mm sq and up UK MoD DefStan wire/cable https://www.elandcables.com/cables/defence-standard-61-12-cable https://www.elandcables.com/media/39719/defence-standard-61-12-part-6-equip… https://www.elandcables.com/media/38355/defence-standard-61-12-part-4-cable… eg the Part4 spec offers 0.055 mm sq (7 x 0.1 mm) and 0.22 mm sq (7 x 0.2 mm), and Part6 carries on with 16 x 0.2 mm for 0.5 mm sq etc Finally, tinned and enamelled copper wire continue to be sold in Standard Wire Gauge (SWG) sizes https://www.engineeringtoolbox.com/swg-standard-wire-gauge-d_1779.html eg https://www.rapidonline.com/unistrand-tinned-copper-wire-62485 and https://www.rapidonline.com/unistrand-enamelled-copper-wire-62484 And, for stranded wire the strands are usu 0.2 mm dia, 0.1 mm dia for the smallest condiuctors HtH; Best Regards Martin -----Original Message----- From: Charles Dickman via cctalk [mailto:cctalk@classiccmp.org] Sent: 07 December 2024 00:10 To: General Discussion: On-Topic and Off-Topic Posts <cctalk(a)classiccmp.org> Cc: Charles Dickman <chd(a)chdickman.com> Subject: [cctalk] European wire size (slightly off topic) How are small wire sizes specified in Europe? I have seen that EN 60228 defines wire cross sections down to 0.5mm2. What about smaller than that? Does the standard go smaller?
